Book excerpt: A love letter to learning and the power of numbers from exciting talents, Rashmi Sirdeshpande and Diane Ewen. A laugh-out-loud 'what if . . .?' adventure that celebrates maths being fun in this riotous read. If a Stegosaurus knew how to do sums - well, what would happen? Maybe she'd learn to code, to invent, to fly to the moon! From the creators of Never Show a T-Rex a Book!
